Why is my Acer AL1516 Monitor not turning on?

If your Acer monitor isn't powering on, try these steps: First, reinsert the power cord and ensure the AC power is within the normal range of 100-240V. Next, reinsert the power cord or check the power section. If those steps don't work, measure the voltage at U701 PIN2 and U702 PIN2, ensuring they are both 3.3V. Also, measure CN701 PIN5/6 to see if it is 12V and CN701 PIN9/10 to see if it is 5V. You may need to check the power section, replace U701 and U702, replace U401, or replace X401.
